Here is how I routed mine. See the blue cap at bottom center of pic? I removed that T from the reservoir and put blue cap on. Follow that vac line toward fan motor. At junction disconnect it and cap. That's the white cap zip tied up at fan motor, sorta near top right in pic. Reroute the line you just disconnected (which goes into cab for HVAC control) straight along fender and plug into reservoir where you originally removed the T. It's tight but a little spit lube will do the trick. Handy retention clip on line fits neatly into available hole in fender. All the other ESOF parts remain so it's quickly reversible.

Basically the T feeds vac to the whole system, and what you are doing is removing the whole mess and plugging only the HVAC into the reservoir.

And as mentioned before if the rubber lines down at the hubs are rotted, remove them and cap off nipple at the hub. Or remove nipple and thread in a brass plug.

Hope that description makes sense.
